please answer There are many ways that people use cocaine. One method is to inject acombination of cocaine and heroin called a Speedball, rather than cocaine alone.What do you predict may happen at the synapses with a Speedball?Both cocaine and heroin will block the dopamine reuptake mechanismOnly cocaine will block the dopamine reuptake mechanismOnly cocaine will affect the number of opioid receptorsBoth cocaine and heroin function will function as antagonistsCocaine and heroin will cancel each other out and have no effect at thesynapses

Speedball: a. A speedball is a mixture of combination of heroin (derived from morphine) and cocaine. b. The combination of both the drugs causes a 'push-pull' reaction that is dangerous for the body. c. When the drug is combined, the side effects primarily negatively impact the brain. d. It leads to various side effects which include: drowsiness, blurred vision, confusion, paranoia, and uncontrollable movements. a. Both cocaine and heroin will block the dopamine reuptake mechanism: Only dopamine can block the reuptake of dopamine because heroin activates dopamine neurons. Option A is incorrect. b. Only cocaine will block the dopamine reuptake mechanism: The function of cocaine is to prolong the dopamine action in the brain by blocking the reabsorption of the neurotransmitters by signaling nerve cells. Option B is correct. c. Only cocaine will affect the number of opioid receptors: Cocaine will not affect the opioid receptors because drugs like heroin bind to opioid receptors and trigger the release dopamine. Option C is also not correct. d. Both cocaine and heroin will function as antagonists: No it is a misconception that mixing heroin with cocaine either balances or cancels the negative side effects of heroin. Option D is incorrect. e. Cocaine and heroin will cancel each other out and have no effect on the synapses: The combination of both the substances is more dangerous and its negative effects are amplified when taken together. Option E is incorrect.
